Abstract

The present invention relates to a kind of preparation method utilizing cow dung to prepare organic fertilizer, comprise the following steps: waste straw, straw are cut into pieces；Then it is added to the stalk being cut into pieces, straw in fresh cow dung, add appropriate urine to mix, at the material that initial fermentation completes, add appropriate leavening, be placed in methane-generating pit and carry out secondary fermentation, form biogas and methane slag, the fermented methane slag completing is filtered, biogas is used as domestic energy, and methane slag takes out, and is dried；Place to normal temperature, then carry out pulverizing, pack, to obtain final product.The present invention utilizes cow dung to prepare the preparation method of organic fertilizer will be used as biogas solution people in implementation process domestic energy after cattle manure, methane slag is treated as fertilizer, plant husbandry can be sufficiently used for, chesson is also helped so that soil is more fertile while the use reducing a large amount of chemical fertilizer.

Description

A kind of preparation method utilizing cow dung to prepare organic fertilizer

Technical field

The present invention relates to fertilizer processing technique field, be specifically related to a kind of preparation side utilizing cow dung to prepare organic fertilizer Method.

Background technology

With the development of China's scale animal and poultry cultivation industry, the generation amount of feces of livestock and poultry is also being continuously increased, in a large number Feces of livestock and poultry after generation if do not carried out harmless treatment, not only can produce foul gas, cause serious environmental pollution, also Can grow mosquito and cause the wide-scale distribution of pathogen, the threat mankind's is healthy.The excrement producing during livestock breed aquatics Just, need to be processed it by rational method；Meanwhile, if because cow dung is dealt with improperly, aquaculture epidemic disease wind is also likely caused Danger outstanding problem, therefore, the key factor being treated as restriction China animal husbandry development of cow dung, had even once caused serious Public health security crisis.

Content of the invention

For solving above-mentioned technical problem, the one that production performance is strong, economic benefit is big that the present invention provides utilizes cow dung system The preparation method of standby organic fertilizer.

A kind of preparation method utilizing cow dung to prepare organic fertilizer, comprises the following steps:

Step one: be cut into pieces waste straw, straw, length requirement is at 2～5 centimetres；

Step 2: be added to the stalk being cut into pieces in step one, straw in fresh cow dung, adds the mixing of appropriate urine all Even, wherein, it is ensured that its cow dung water content is between 40～60%；Pile up static 2～5 weeks, complete initial fermentation；

Step 3: the material completing in initial fermentation, adds appropriate leavening, is placed in methane-generating pit and carries out secondary fermentation, leavening Usage amount be: 0.1-2%；Described leavening is: cow dung special leaven, and fermentation time is: 6～8 weeks;

Step 4: in step 3, during the fermentation, forms biogas and methane slag, carries out the fermented methane slag completing Filtering, biogas is used as domestic energy, and methane slag takes out, and is dried；Place to normal temperature, then carry out pulverizing, pack, to obtain final product.

The present invention utilizes cow dung to prepare the preparation method of organic fertilizer will be as biogas after cattle manure in implementation process Solving the domestic energy of people, methane slag is treated as fertilizer, can be sufficiently used for plant husbandry, reduces making of a large amount of chemical fertilizer With while also help chesson so that soil is more fertile.To protecting ecology, environment is kept all to have great meaning Justice, meanwhile, has been effectively ensured plant and has kept that environment is clean, cleaning.

Detailed description of the invention

Being described the principle and feature of the present invention below, example is served only for explaining invention, is not intended to limit Protection scope of the present invention.

Some soil, when planting agricultural product, become bulk to harden together, it is impossible to well to give birth to crop Long environment, goes down for a long time, directly affects the harvest of later stage crop.Therefore, when planting crop, the use of fertilizer is very Crucial.

A kind of preparation method utilizing cow dung to prepare organic fertilizer, comprises the following steps:

Step one: be cut into pieces waste straw, straw, length requirement is at 2～5 centimetres；

Step 2: be added to the stalk being cut into pieces in step one, straw in fresh cow dung, adds the mixing of appropriate urine all Even, wherein, it is ensured that its cow dung water content is between 40～60%；Pile up static 2～5 weeks, complete initial fermentation；

Step 3: the material completing in initial fermentation, adds appropriate leavening, is placed in methane-generating pit and carries out secondary fermentation, leavening Usage amount be: 0.1-2%；Described leavening is: cow dung special leaven, and fermentation time is: 6～8 weeks;

Step 4: in step 3, during the fermentation, forms biogas and methane slag, carries out the fermented methane slag completing Filtering, biogas is used as domestic energy, and methane slag takes out, and is dried；Place to normal temperature, then carry out pulverizing, pack, to obtain final product.

The present invention utilizes cow dung to prepare the preparation method of organic fertilizer will be as biogas after cattle manure in implementation process Solving the domestic energy of people, methane slag is treated as fertilizer, can be sufficiently used for plant husbandry, reduces making of a large amount of chemical fertilizer With while also help chesson so that soil is more fertile.To protecting ecology, environment is kept all to have great meaning Justice, meanwhile, has been effectively ensured plant and has kept that environment is clean, cleaning.

Protection scope of the present invention is not limited only to the technical scheme disclosed in detailed description of the invention, the foregoing is only the present invention's Better embodiment, is not limiting as the present invention, every according to technical scheme above example is made any carefully Micro-modification, equivalent and improvement, should be included within the protection domain of technical solution of the present invention.
